Heidi Klum enlisted Sia to help her heat up the screen to promote her lingerie line.

The supermodel and "Game of Thrones" star Pedro Pascal portray lovers in a new video to promote Heidi Klum Intimates Lingerie, set to the pop star's song "Fire Meet Gasoline."

But the couple's steamy romance takes a dark turn when Klum is shown setting their house on fire.

After committing arson, she dons a Sia-like wig and walks into the arms of her lover as he watches their home burn down.

Klum said she was "thrilled" to have Sia's song featured in her video.

"Sia is one of those incredible artists who puts so much passion into her work," she said in a statement.

"I remember being blown away the first time I heard her voice on 'Breathe Me," she added. "I love great collaborations and to be given the opportunity to appear in the video while wearing my Heidi Klum Intimates collection, is definitely up there.

"(Director) Francesco (Carrozzini), Pedro and I had a blast shooting," she added about the sexy video.
